Please help me !

So I use to 날짜 a guy then he said we are better just like friends. so now we're just 프렌즈 but what he doesn't know is that I still 사랑 him. Everytime I see him and everytime he talks to me I feel like i'm gonna breakdowm. And the worst part is that he's dating another girl.
How can I get over him ? PLEASE HELP ME :-(
